COMBINATION ADJUSTABLE AND CONVERTIBLE SCHOOL DESK AND SEAT.

Application filed March 21,

- justable and Convertible School Desk and Seat, of which the following is a specification.

The main object of our invention is to provide a simple but strong construction which is adaptable to the various conditions required in different schools and which can be made at reasonable cost, readily set up and adjusted when necessary and which is free of unnecessary parts and is sanitary.

In accomplishing these objects we provide a cylindrical standard and mount upon it the desk and the seat. The standard is preferably formed in two parts surrounded by two clamps. Each clamp is preferably formed in two parts, the desk being carried by one part of one clamp, and the seatbeing carried by one part of the other clamp. vBy this construction the seat and desk may be independently attached or detached or adjusted. By this construction it is also possible to-divide the standard, secure the desk to one half of the standard and secure the seat to the other half of the standard, thus making two independent elements. Preferably, the seat and back are connected together; the seat may be adjusted forward and back and the back of the seat may be adjusted up and down. Preferably, they are mounted so that they may be swung from one side to the other side.

Figure 1 is a side view of a construction embodying the improvements of our invention.

Fig. 2 is a plan view of the same, showing the seat in dotted lines in another position.

Fig. 3 is a horizontal section on the plane of the line 3-3 of Fig. 1.

Figs. at and 5 are side views respectively of the construction separated into separate parts forming a desk and a seat separately.

Fig. 6 is a section on the plane of the line 6-6 of Fig. 4.

Fig; 7 is a plan View and section on the plane of the line 77 of Fig. 5.

The standard is formed in two parts 10 and '11 which are similarly constructed and preferably provided with interfitting tongues and grooves 12 -12. This standard has senti nt-Qatar portions is and is Specification of Letters Patent.

adapted to be secured to the floor in any suitable manner.

The desk 15 and the seat 16 are adapted to be secured to the standard by specially independently of each other. The clamping device for the desk consists of three parts, 17-18 and 19 secured together by bolts such as 20 and 21 on opposite sides of the standard or post. The clamping member 17 has one or more braces 22 secured to the desk and the clamping member 18 has one or more braces such as 23 secured to the desk. It will be obvious that the members 17 and 18 may be formed in one piece.

The clamping device for the seat consists of the parts 24. and 25 secured together by pairs of bolts suclr as 26 and 27. A bracket 28 is pivotally mounted in a socket 29 so that the seat may be swung from one side to the other. 1 1

Preferably, an adjustable clamping device 30 is provided to secure the seat to the bracket 28 so that the seat can be adjusted forward and back with relation to the post so as to vary the position of the seat with relation to the desk in front (not shown). The seat also has a back 31 supported by one or more spring arms 32. These arms are preferably secured to the seat as at 33 by a clamping device so that the back may be ad justed forward and back with relation to the seat. Similarly, the back is preferably secured to the arms by clamping devices such as 34 so that the back may be adjusted up and down with relation to the seat. The

'back and seat both being secured together in this way, when the seat is swung the back swings with it, as for instance, shown in dotted lines in Fig. 2, so that the scholars can turn their seats for instance to look at a side black-board and of the back.

lVith this construction it will be seen that the seat and desk can be secured to or detached from the standard independently of each other and adjusted independently to accommodate different conditions. If necessary, the seat can be entirely removed leaving the desk alone on the standard where for instance it is desired to use the desk for a frontrow. Similarly, the desk may be removed and the seat alone used, for instance, for the rear row of seats.

still have the support I The full clamping device as heretofore drical standard or post and may be adjusted not only up and down but at any angle on the post. By constructing the post or standard in two parts, it is possible to separate the parts and mount the desks and chairs on the Separate parts as shown in Figs. 4: and 5, sothat two units are made from one. In this case it is preferred to substitute flat clamping members 35 and 36 for the semicylindrical members 19 and 2 5 respectively. In this case of course the clamping devices and the parts carried thereby cannot be 1'0- tated on the standard, but they can be adjusted up and down as heretofore described.

The parts are so designed and constructed that the standard and clamping devices and brackets may be conveniently made of cast iron or malleable iron or steel, or of sheet steel if desired. Although we intend that the clamping devices shall be so designed and constructed as to hold the desk and seat on the standard without the use of set screws, we do not intend to be limited to such a feature.

l/Ve claim:

1. A combined desk and seat construction comprising a standard, two clamps secured thereon, each clam'p being formed of two separate parts, means for securing the parts together, a desk carried by one part of one clamp and a seat carried by the other part of the other clamp, said clamps being independently adjustable and detachable.

2 A combination desk and seat construction comprising a vertically divided standard formed of two similar parts, each part having a base adapted to rest on the floor independently of the other part, a desk, means for adjustably supporting said desk on said standard, a seat, and means for adjustably supporting said seat on said standard, one of said supporting means also securing the parts of said standard together.

3,. A combined desk and seat construction comprising a post formed of two similar parts, a desk, a seat, and means for securing said desk and seat to said post independently of each other, said desk and seat being adapted to be interchangeably adapted to said post or to either part of said post.

4. A combined desk and seat construction comprising a cylindrical standard, two separate clamping devices mounted on said standard and independently adjustable vertically and horizontally thereon, one above the other, a desk carried by the upper clamping device, said lower clamping device having a vertical socket near the standard, a bracket removably and pivotally supported at its rear end in said socket and adapted to swing horizontally, a seat carried by said bracket and adapted to swing horizontally therewith in relation to said desk and a back carried by said seat but movable with relation thereto.

5. A combined desk and seat construction comprising a post formed of two vertically extending parts, two clamping devices independently secured to said post and removable therefrom independently, each clamp-- ing device being formed of two parts, one part of each clamping device being interchangeable with the corresponding part of the other clamping device, and a desk and seat respectively carried by the other part of each clamping device.

6. A combined desk and seat construction comprising a post, two clamping devices independently secured to said post and removable therefrom independently, each clamping device being formed of two parts, one part of each clamping device being interchangeable with the corresponding part of the other clamping device, and a desk and seat respectively carried by the other part of each clamping device.

7 A combined desk and seat construction comprising a vertically divided post formed of interfitting parts, a desk, means for securing said desk to said post or to either part thereof, a seat, and means for securing said seat to said post or to either part thereof independently of the desk.
